Loose Housing Means Less Labor
Using a loose housing system for your dairy enterprise can mean a minimum of chore labor for you. But it takes careful planning and figuring to do the job right and avoid disappointment
Sixty Years of Change in Tree Numbers and Basal Area in Central Utah Aspen Stands
Plots established in three separate aspen stands in central Utah were inventoried at irregular periods over a 64 year period
Evolution of Subjective Hurricane Risk Perceptions: A Bayesian Approach
This paper studies how individuals update subjective risk perceptions in response to hurricane track forecast information, using a unique data set from an event market, the Hurricane Futures Market (HFM). We derive a theoretical Bayesian framework which predicts how traders update their perceptions of the probability of a hurricane making landfall in a certain range of coastline. Our results suggest that traders behave in a way consistent with Bayesian updating but this behavior is based on the perceived quality of the information received.risk perceptions, learning, Bayesian learning, event markets, prediction markets, favorite-longshot bias, hurricanes
A domain-specific analysis system for examining nuclear reactor simulation data for light-water and sodium-cooled fast reactors
Building a new generation of fission reactors in the United States presents
many technical and regulatory challenges. One important challenge is the need
to share and present results from new high-fidelity, high-performance
simulations in an easily usable way. Since modern multiscale, multi-physics
simulations can generate petabytes of data, they will require the development
of new techniques and methods to reduce the data to familiar quantities of
interest (e.g., pin powers, temperatures) with a more reasonable resolution and
size. Furthermore, some of the results from these simulations may be new
quantities for which visualization and analysis techniques are not immediately
available in the community and need to be developed.
This paper describes a new system for managing high-performance simulation
results in a domain-specific way that naturally exposes quantities of interest
for light water and sodium-cooled fast reactors. It describes requirements to
build such a system and the technical challenges faced in its development at
all levels (simulation, user interface, etc.). An example comparing results
from two different simulation suites for a single assembly in a light-water
reactor is presented, along with a detailed discussion of the system's
requirements and design.Comment: Article on NiCE's Reactor Analyzer. 23 pages. Keywords: modeling,

The Stadium Interstate Freeway and Cedarburg Bog
Although the initially favored corridor for the Stadium interstate freeway was adjacent to Cedarburg Bog, the highway department is now favoring a route at least a mile from the Bog. Many different individuals had written highway officials stressing the scientific, educational and recreational value of the Bog. It is appropriate that the highway officials of a state which has been a leader in preserving natural areas for scientific and educational use should show concern with preserving Cedarburg Bog as a wilderness area. A hearing about the proposed route will be held July 10 in Ozaukee County, and testimony will be presented stressing the value of the Bog and the importance of not having a highway in close proximity
Semi-relativistic charge-current density operator
The charge-current density and two-photon operators consistent with a
single-particle semi-relativistic Hamiltonian are derived within a suitable
functional derivative formalism which preserves gauge invariance. An
application to electron scattering is presented and results are compared with a
fully relativistic case and the non-relativistic cases corrected through fourth
order in M^{-1}.Comment: 20 pages, 3 postscript figures, typos correcte
